This is what we have so far for ACM: https://docs.google.com/spreadsheets...#gid=338817466
to make this work you would need "variable" low level output... I just dont see how to send a flat signal...
Will coding this make away with the sony amp and install a "proper" audio setup with a clean signal to start?
Thanks Livnitup! great work man!

I am not fluent yet on Forscan... but it looks like you nailed it?

LOL...
I think we can help each other out... sorry for my English is not my primary language.
Currently on the F150 if you add separate audio system "upgrade" to your Sony system you will have to grab the signal AFTER the OEM Sony amplifier, which means that the aftermarket amplifiers will feed of the wires that go from the OEM Amp to the speakers.
When you do this there is specific vehicle equalization thats been done by the ACM and also noise/distortion from the OEM amplifier, basically the audio signal gets "Dirtier" everytime is touched by the OEM ACM and Sony amp. So if you add all your expensive aftermarket stuff after this you will have garbage in and garbage out.
Current ACM programming is to output "low level fixed signal equalized" which means the signal is less than 5V (what most oem and aftermarket amplifiers take as input) and the volume is constant, what makes the volume go up and down as you turn the volume **** is the can bus giving the OEM Sony amp the instruction to increase or decrease its output to the speakers. Also the signal is equalized from the ACM to best suit the truck interior, speakers and to protect them at high volumes by limiting bass which could destroy them.
In order to get a clean signal you would need to reprogram the ACM to output a "low level unequalized signal variable". Which means low power so that any aftermarket amp can receive it + unequalized which means all frequencies are flat and not exaggerated to compensate for vehicle or speaker shortcomings so with this you get a basic "standard" signal so to speak and Volume Variable which the ACM now increases or decreases the low level signal that is being sent to the amp so that any aftermarket amp works with the volume **** on your F150.
With this ACM "reprogram" you could scrap all the oem audio equipment starting with the Sony amp and You will only be left with a basic signal coming from the ACM (4 channels FR, FL, RR and RL) so that you can add all the aftermarket processors, amplifiers and speakers that you wish and suit them to your taste in audio getting a clean untouched signal.
Let me know if I was able to explain myself.

So maybe something to try would be 727-01-01 is xx5x xxxx xxxx (5=Front: External Variable & Rear: External Variable)?
Do you have a way to test this value to see if in fact it's giving a "basic signal"? You explained everything well but I still don't which option to change in FORScan there will achieve the results you're after and I have no way to test. Please let us know what you find.

Ok, I have the Sony system and my value at 727-01-01 is xxAx xxxx xxxx (Front: fixed L/L & Rear: Fixed L/L)
So maybe something to try would be 727-01-01 is xx5x xxxx xxxx (5=Front: External Variable & Rear: External Variable)?

It's my first day
I played around with Secure Idle and tossed my FOB out the window while driving to see what would happen, all while rambling on about it into my iPhone.
I posted this on youtube if anyone cares to know more.

I didn't think about that. Secure Idle works for me, and if I try to shift without the fob in the vehicle, a message pops up on screen, "no key detected." So I guess I thought the shift lock release button wasn't what was preventing the shifter from moving, but now I'm curious.
